我尝试过使用showValues:在选项中为true,但没有运气。 这是图书馆http://krispo.github.io/angular-nvd3/#/ showValues适用于离散条形图,但不适用于多重条形图。This is the expected output

此代码适用于我。
1)在图表选项后调用函数( setOnTopLabel(); ) 配置。
2)在你的js代码中添加这个函数。
function setOnTopLabel() {
$timeout(function () {
debugger;
d3.selectAll('.nv-multibar .nv-group').each(function (group) {
debugger;
var g = d3.select(this);
// Remove previous labels if there is any
g.selectAll('text').remove();
g.selectAll('.nv-bar').each(function (bar) {
var b = d3.select(this);
var barWidth = b.attr('width');
var barHeight = b.attr('height');
g.append('text')
// Transforms shift the origin point then the x and y of the bar
// is altered by this transform. In order to align the labels
// we need to apply this transform to those.
.attr('transform', b.attr('transform'))
.text(function () {
// Two decimals format
return parseFloat(bar.y);
})
.attr('y', function () {
// Center label vertically
var height = this.getBBox().height;
return parseFloat(b.attr('y')) - 10; // 10 is the label's magin from the bar
})
.attr('x', function () {
// Center label horizontally
var width = this.getBBox().width;
return parseFloat(b.attr('x')) + (parseFloat(barWidth) / 2) - (width / 2);
}).style("fill", "black").style('stroke-width', "10").style('fill-opacity', "100");
});
});
}, 1000);
}
